The researchers next want to look into what happens when engineers inject liquid carbon dioxide from power plants deep underground in an attempt to keep the carbon from entering the atmosphere.

Carbon dioxide is like nitrogen in many ways, but if it is mixed with limewater, it causes the clear liquid to because milky, while nitrogen dose not. This is the test for carbon dioxide.
